"Some shark populations in the Mediterranean Sea have completely collapsed, according to a new study, with numbers of five species declining by more than 96 percent over the past two centuries.
...Particularly troubling, the researchers said, were patterns indicating a lack of females of breeding age, which are essential if populations are to recover even with new conservation measures.
Sharks take years to reach sexual maturity and, unlike most other fishes, produce small numbers of young, making them particularly vulnerable to overfishing. Populations have declined worldwide, but experts say the Mediterranean — bordered by many countries with diverse rules and fished intensively for centuries — has had bigger losses of sharks and other large predatory fish, including tuna."

"There are great whites off the coast of New England, although the species is relatively rare," he said.
"I did not observe the animal or animals myself, but the two people who reported them are experienced, credible sources."
The accounts by Capt. Buddy Vanderhoop of Aquinnah and Capt. Scott McDowell of Chilmark are similar. Both described an animal around 15 feet long and wide in girth." Link
